A ridge of high pressure responsible for setting scores of daily temperature records across B.C. since last Friday did so again Thursday before moving eastward.
In all, 21 areas within the Interior set daily highs for May 4, with Cache Creek being B.C.’s hotspot at 32.7 degrees Celsius. That eclipsed the town’s previous record of 30.0 C., which was set in 1998.

As a result of the hot weather, rapid mountain snowmelt has been prominent for the past several days. However, cooler weather is en route, with increasing showers or thunderstorms rolling in from Idaho and eastern Washington.
The switch from very high temperatures and rapid snowmelt to increasing rainfall in the Southern Interior will result in continued high risk of localized flooding across the region through the weekend.
Below are the communities that recorded new daily highs on Thursday, May 4, 2023.
